Cory Doctorow: Brendon sez, "Zotero is a very interesting Firefox-based browser that has been modded to accomodate the needs of scholars and infovores. It basically pulls a bunch of research tools into one browser, for the benefit of humanities scholars who get easily confused. Supports export to EndNote, storage capability, ability to search through your collections of stored data, etc."
